After training batting early with batting coach Kim Han-soo, he is eager to train defense such as blocking with battery coach Serizawa Yuji.

After running, he participates in the analysis of pitching and catcher power and studies how to target opponents.

"I'm having fun every day," Kim Ki-yeon said at Jamsil Stadium in Seoul on Sunday. "I'm really happy because I have a lot of chances to play. Even when I don't play, I learn from Yang Eui-ji, the best catcher. I'm so happy."

Doosan, who found the "Successor of Yang Will," also laughs at Kim Ki-yeon.

Until the 21st, Yang Eui-ji wore a catcher's mask for 218 ⅔ innings.

Kim Ki-yeon worked 160 innings as a catcher to ease Yang Eui-ji's burden.

In particular, Kim Ki-yeon is playing the role of the "main catcher" after Yang Eui-ji was hit by a batter's ball against the KIA Tigers on the 15th.

Kim Ki-yeon started as a catcher for five consecutive games from the KIA match on the 16th to the SSG Landers match on the 21st.

Doosan manager Lee Seung-yeop said, "As Yang Eui-ji is feeling pain in his knee, Kim Ki-yeon will continue to play as a catcher for the time being."
